What to check before the MOT
Built from this model's own failure record, not general advice.
- Start with missing - it accounts for 32.3% of failed tests on this model.
- Then check not working and too high, the next two most common reasons.
- Age matters here: 68.95% of 6-10 year old examples pass, against 51.61% at 11-15 years - a gap of 17.3 points.
- The most common advisory is noise is clearly in excess of that emitted by a similar motorcycle fitted with a standard silencer in average condition (15.1% of all tests) - not a failure, but money you will spend sooner or later.
- Average recorded mileage at test is 17,473 miles, which is the number to compare any advert against.

|---|---|---|---|
| 6-10 years | 68.95% | 1,388 | |
